How does a Hydrogen water bottle work


A hydrogen water bottle operates by electrolysis. An electric current runs through two electrodes separated by a Proton-Exchange Membrane (PEM) or Solid Polymer Electrolyte (SPE), breaking down water molecules (H2O) into hydrogen (H2) and oxygen (O2). The oxygen is expelled, and the hydrogen bubbles into the water where it partially dissolves.

Unlike carbon dioxide, hydrogen gas doesn't dissolve well in water and doesn’t cause fizziness. However, its small molecular size allows it to penetrate cell membranes and mitochondria easily, making it effective even at low concentrations measured in parts per billion (ppb).


To increase hydrogen solubility, hydrogen water generators apply Henri's law by increasing pressure within the bottle. This allows the water to dissolve more hydrogen gas, resulting in a dissolution rate up to ten times that of some natural springs and twice that of magnesium-based hydrogen tablets.

The pressure chamber, airtight cap, and pressure release valve are crucial design features. Activating the device once elevates pressure sufficiently to dissolve up to 3000 ppb of hydrogen. A second activation without releasing pressure can infuse water with up to 5000ppb of hydrogen. However, exceeding this limit or initiating additional cycles without opening the cap can damage the device. Even with a safety valve, it's recommended to periodically release pressure by opening the cap.


The automatic valve in the cap works by compressing a spring over a small hole, which must remain unobstructed. Overfilling with water can hinder the valve's operation.

Water quality impacts the concentration of hydrogen-enriched water produced. Purified or distilled water holds more hydrogen and is preferred for membrane longevity, but tap or mineral water can also be used.


Hydrogen molecules neutralize harmful free radicals (oxidants produced as a byproduct of cellular activity). Hydrogen selectively targets only the excess radicals, transforming them into water – a "selective antioxidant." This property aids cellular hydration and detoxification.

Let's take the hydroxyl radical (OH•), a common harmful free radical:

OH• + H2 → H2O + H
In this example, the hydrogen molecule neutralizes the hydroxyl radical to form water (H2O) and a hydrogen radical.

Free radical reactions often involve chain reactions, making the complete process more complex than a single equation.
The hydrogen radical (H) formed in the reaction is also a radical. However, it's less reactive than many other harmful free radicals and can be further neutralized through other processes within the body.


Our cells need water, oxygen, and hydrogen. While water is composed of these elements, they are not directly accessible in their molecular form. Just as our lungs extract oxygen, our gut bacteria generate hydrogen essential for cellular processes.

Oxygen supplementation via nasal cannula is common for respiratory patients. Similarly, hydrogen can be supplemented by inhaling gas or dissolved in water for absorption through the digestive system.

Hydrogen is a supplement, and a hydrogen water bottle is a mobile supplement creator. The term "hydrogen water bottle" can be misleading – it's a device that generates hydrogen-infused water.
